JET DYEING- APPARATUS AND PROCESS.

Application filed April 13, 1923.

This invention relates to a winding and dyeing apparatus, and more especially in some of its more specific details to a jet dyeing apparatus for dyeing textiles or the like.

It is a general object of the invention to provide an improved apparatus of the class mentioned which is efiective and reliable in operation, simple in construction and comparatively inexpensive in production costs.

Another object is the provision of an improved winding and dyeing apparatus for random application of dye to yarn or the like in which the application of the dye is readily controllable, and being adapted for ready application to existing winding apparatus without much trouble and little rearrangement of parts.

Another object of the invention is the provision of an improved dyeing apparatus for applying dye to a traveling thread by projection of a jet or spray directly thereon.

Another object is to provide an improved process for the continuous or random application of dye to textiles whereby predetermined effects are readily obtainable.

Other objects will be in part obvious in connection wi h the following detailed de-' scription and in part. pointed out in connect i on therewith.

The invention accordingly comprises the several steps and the relation and order of one or more of such steps with respect to each of the others, and the apparatus embodying features of construction, combinations of elements and arrangement of parts which are adapted to effect such steps, all as exemplified in the following detailed disclosure, and the scope of the application of which will be indicated in the claims.

For a more complete understanding of the nature and objects of the invention, refer ence is had to the following detailed description and to the accompanying drawings, in which,

Fig. 9 is a view similar to Fig. 7, but showing a still further modified form.

Referring now to the drawing for a detailed description of the embodiment of the invention there illustrated, a combined winding and dyeing unit is shown in Fi 1, being provided with a supporting frame 10, carrying a rotatable spindle 11, adapted to carry a bobbin or support 12 rotatable with the spindle, and having a conical base 13. A vertically oscillatable member or rail 14 is supported by the frame 10, adjacent the spindle carrying a tnreaded upright rod 15, which carries a friction winding cup or nut 16 having a conical exterior surface for contact with the conical winding field 17 of the yarn or thread reposing 0n the bobbin. it is to be understood that the yarn, while being wound on to the bobbin, is distributed over the conical winding surface by the oscillating up and down movement of th rail 14, which moves over a vertical. di. ance equal to the altitude of the conical surface. As the bobbin fills with yarn near the base thereof, the winding cup 16 will engage frictionally therewith, rotating it. for upward adjustment on the threaded rod 15. in this manner the wound yarn presents a cylindrical surface at the base of the spindle, gradually increasing in altitude as the winding progresses, while the winding field 1'? will remain conical throughout the winding operation, moving upwardly toward the top of the bobbin, until the winding is completed. Furthermore, it will be understood that the traveling thread will be carried over the conical surface by the up and down movement of the rail 14. It will also be understood by those skilled in the art that this type of winding apparatus is capable of winding at a rapid rate, thus causing the thread, both as it approaches the cone and in wound position on the cone, to travel at a rapid rate.

Any desired: number of spindles such as above mentioned may be mounted in .a series along the frame 10, and the rail 14 may be extended along this series of spindles carry ing a threaded rod 15 for each spindle. As will be understood, all of the spindles with their winding mechanism may be operated together, forming a series of simultaneously operating winding units. The spindles-are operated by a suitably driven mechanism, and the rail 14 is caused to oscillate up and down by a power driven cam mechanism, such as indicated diagrammatically at 18 in I Fig. 1.

The dyeing apparatus is arranged in the embodiment shown to apply dye directly to the yarn after it has come to rest on the conical winding field of the bobbin, but may be arranged to apply the dye directly to the traveling thread A before it reaches the conical winding surface. his apparatus includes a swinging supporting guiding frame 19, forming a part of the winding mechanism, and having upper and lower spaced arms supported on the threaded rod 15. The lower arm is slidably connected to the rod 15 through a bushing 20 contacting with the threads, while the upper arm is connected through a sleeve 21 having a smooth interior surface contacting with the threads, the upper arm being rigidly secured to this sleeve. The sleeve is connected to the threads by a manually releasable spring pressed thread engaging member 2-2, as shown in Fig. 2, which may be released at will to permit vertical adjustment of the frame along the threaded rod. As shown in Fig. 2, the Winding cup 16 is securely attached to the sleeve 21.

The swinging frame or bracket 19 carries a jet valve 23 normally lying adjacent the surface of the winding field of the bobbin, and in theembodiment shown in Figs. 2, 5 and 6 includes a stationary part 24 with a dye reservoir 25 and a conduit 26 leading thereto from a source of supply. A port 27 leads from the dye reservoir to the face of the stationary valve part, and a rotary valve part 28 is mounted tightly against the part 24 on a supporting pin 29 threaded into the stationary valve part, and at its opposite end into the upright member 30 of the swinging bracket. The rotary valve member 1s normally held in tightly mating position with respect to the stationary part by a spring 31 secured at one end to the rotary valve part and at its opposite end to a collar 32 fixed on the supporting pin 29. The rotary valve part is provided with a jet port 33, and the spring 31 not only holds the valve parts in mating position to provide a liquid tight joint, but also biases the rotary partso the valve ports 27 and 33 are out of alinement and the dye jet thus cut off. The jet port 33 may be shaped to form a jet or small concentrated stream of dye, which will be supplied to the dye valve under pressure, or it may be formed to atomize the dye passing therethrough so as to apply it to the textile in the form of a spray.

For operating the jet valve to open the same to flow dye as desired a mechanism is provided preferably controlled by the winding mechanism. In the embodiment shown, this operating mechanism includes a rotary friction wheel 34 carried by the swinging frame 19 and providedwith a conical friction surface for frictional engagement with the conical winding field of the bobbin.

This friction wheel carries a tappet 35 lying in position to engage at each revolution with the radial arms of a star wheel 36 supported on a stud 37 carried by the swinging 'rame. A ratchet Wheel 38 is mounted to rotate with the star wheel, a spring detent 39 lying in position to engage the teeth of the ratchet wheel to prevent reverse rotation. A cam 40 is also carried by the star wheel lying in position to engage an arm 41 carried by the movable valve part 28. It will therefore be seen that as the friction Wheel rotates, the cam will be brought successively into position to open, or partially open, the valve ports to provide an intermittent jet application of dye to the traveling textile. A pin 42 is fixed to the stationary valve part en gaging in a slot 43 in the movable valve part to limit rotation thereof in either direction. This arrangement supports the operating arm 41 in proper position for engagement with the cam 40.

It will be noted that it will be necessary for the swinging frame 19 to swing on its vertical axis as it oscillates up and down during the winding operation in order that the friction wheel .34 may be always in frictional engagement with the .conical winding field, and in order that the dye applicator may be always in proper position relative to the textile for eflicient application of dye.

Means for taking advantage of the tension of the running thread is provided for this purpose, including an inner lever arm 44 rigidly attached to the sleeve 21. and an outer lever arm 45 pivoted to the first arm, and carrying at its free end a guiding and supporting roller 46, lying normally in position to contact with an abutment post 47, which is long enough to extend over the normal vertical travel of the swinging frame. The outer lever arm has an upwardly extending lug 48 pivotally supported on which is a yarn supporting and guiding lever 49, having an angularly disposed arm 50 lying in position to contact with the lever arm 44. a

sleeve 51, which may be replaced by a shorter or longer sleeve to increase or diminish at will the force transmitted to the swinging frame from the traveling yarn. The yarn supporting lever is provided with an extenthe reactive force due to this action. Should all 5 the thread break or become suiiiciently slackened, the yarn lever 49 will be released to upward movement, and the lever arm 45 will then be permitted to swing around its pivotal connection with lever arm 44;, thus permitting the frame 19 to swing away from the bobbin; the intermittent application of dye is thus discontinued,'until the apparatus isreset.

The operation of the device is embodied in the foregoing description. It is specially noted, however, that the rate of travel of the thread A will vary, reaching a maximum when winding at the base of the conical winding surface and a minimum when winding at the apex thereof. However, due to the fact that the jet dye applicator is controlled directly from the conical winding field, it will be seen that the application of dye will be proportional to the rate of travel of the thread throughout the windingoperation, that is, the amount of dye applied per unit length of thread will be varied with the rate of travel of said thread. It will be observed that when the speed of the thread varies, the speed of the cam 4:0 carried by the star wheel 36 also varies. Therefore, to

- take a specific instance, when the speed of the thread doubles, the speed of the cam also doubles, so that the frequency of the jets likewise doubles, and therefore the number ofjets per unit length of thread wound remains constant. The length of each patch or streak of dye applied to the thread also re mains substantially constant or uniform, since, although the jet valve remains open only approximately half as long at each valve opening, the speed of the thread is twice as great. Also since the rate of dye flow through the valve is substantially constant with a given dye pressure, it will be seen that the amount of dye per unit length of thread wound will be only half as great; that is, the amount of dye applied per unit length of thread wound is less as the rate of thread travel increases, or, in other words,

the proportion of dye applied is less as the speed increases. It is in this sense that the term proportionately and similar expressions are employed in the claims. This variable application of dye to the thread is effective to produce the desirable mottled or variegated effect when knit into garments. It is also to be noted that the valve mechanism nay be readily adjusted and controlled to a nicety, and desired eifects thus obtained. The dye being under pressure as stated, the jet is given a velocity whereby to cause the dye to strike the thread with some force so as to penetrate the fibers of the textile. Since the cam i0 is stopped and started ver 7 abruptly by the operation of the tappet upon the star wheel 36, and, moreover, since the cam 40 is provided with abrupt terminals, it will be seen that the valve is opened and closed with a quick action to start or stop the jet very abruptly. Thus the dye is applied uniformly during the operation of the jet and dribbling is avoided at both the start and finish of jet operation.

In the modified form of the invention illustrated in Fig. 8, the operating mechanism for the jet valve is similar to that previously described, being indicated by the same reference characters with exponents a. In this case, however, the valve 23 itself is modified, the stationary part 2 L" thereof having four pipes 54 leading thereto instead of only one as in the former case. Each of these pipes may lead to sources of different colored dye supply so jets of dilferent colors may be projected upon the yarn. The movable part of the valve is provided with jet openings corresponding to the supply pipes 54, these openings being indicated in dotted lines in Eig. 8 at 55. These jet openings are spaced similarly to the spacing of the pipes 54 and when the movable part of the valve is in normal or unoperated position as shown the jet openings are disaligned with respect to pipes 541 and flow of dye cut oft", but when the valve is operated. as when the cam 40 engages the follower arm ll the jet openings will be moved respectively to align with the pipes; in this manner jets of dyes of different color may be projected simultaneously. It will be understood that the corresponding jets and pipes will be connected so the different colored dyes will not mingle in the operation of the valve.

In the modification of the invent-ion illustrated in Fig. 9, the operating parts for the valve, again, are similar to those disclosed in the first modification, being designated by the same reference numerals with exponents b. The stationary part 24 of the valve, however, is provided with four dye supply pipes 57, 58 and 59 leading thereto, but a greater or lesser number may be employed desired. These pipes may conduct dyes of different color to the jet valve as in the modiiication of Fig. 8. In this embodiment of the invention the cam 40" is modified, hav ing an elongated working face cooperating with the follower arm all in several different positions to hold the movable part of the valve temporarily in different positions. The movable part of the valve is provided with jet openings 60 and 61, the opening 60 being spaced from opening 61 slightly less than 180 degrees and lying, in unoperated or normal position of the valve, adjacent to the pipe 56, but slightly spaced therefrom to prevent flow of dye. In normal position of the valve the jet port (31 is spaced some distance from the pipe 58, but this spacing is greater than the spacing between port 60 and pipe 56 as will be obvious from the drawing.

In operation of the modified form of the invention of Fig. 9, the star wheel 36" is given a. step by step movement in a manner similar to that described above, the elongated cam face of cam 40" engaging with the follower arm 41 of the valve to move the latter step by step to different corresponding positions. In Fig. 9 the valve is shown in closed or normal position with the inclined part of the cam about to engage with the follower arm 4r. The next succeeding step of the L cam 40 willmove the jet port into alignwith pipe 58; while at the fourth succeeding step jet port 61 moves into alignment with pipe 59, while port 60 passes beyond pipe 57, cutting off dye flow therefrom. It will therefore be seen that the jet ports 60 and 61 will be opened to flow of dyes of different color therefrom, alternately and successively at the different steps of movement of the operating cam 40. At the fifth step of operation of the mechanism, following the fourth step as described, the follower arm 40 passes beyond the inclined cam surface, and the valve is automatically moved again to initial position as shown in Fig. 9 under influence of the operating spring 31.

The embodiment of the invention shown in Fig. 9 provides for four different colors of dyes to be projected in successive jets, but there may be more or less than four pipes and the jet ports may be correspondingly arranged.

Since certain changes in carrying out the above process and in the constructions set forth, which embody the invention may be made without departing from its scope, it is intended that all matter contained in the above description or shown in the accompanying drawing shall be interpreted as illustrative and not in a limiting sense.

It is also to be understood that the following claims are intended to cover all of the generic and specific features of the invention herein described, and all statements of the scope of the invention which, as a matter of language, might be said to fall therebetween.
